Rose plant named ‘Evera 108’

ABSTRACT

A new and distinct cultivar of rose plant named ‘Evera 108’, characterized by its upright, compact and rounded plant habit; dark green-colored leaves; large bright double yellow-colored flowers with numerous petals per flower; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Evera 108’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the Roseclass, botanically known as Rosa hybrida, commercially known as a pottedRose and hereinafter referred to by the name ‘Evera 108’.

The new Rose plant is a product of a planned breeding program conductedby the Inventor in Denmark. The objective of the breeding program was todevelop new potted Rose cultivars with novel and attractive flowercolors, disease resistance and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by theInventor on Mar. 1, 2002 of two unnamed proprietary Rosa hybridaseedlings, not patented. The cultivar Evera 108 was discovered andselected by the Inventor as a flowering plant within the progeny of thestated cross-pollination in a controlled environment in Denmark. Plantsof the new cultivar differ primarily from plants of the parentselections primarily in flower color.

Asexual reproduction of the new Rose plant by cuttings in Denmark sinceNov. 20, 2003, has shown that the unique features of this new Rose plantare stable and reproduced true to type in successive generations ofasexual reproduction.

SUMMARY OF THE INVENTION

The new Rose plant has not been observed under all possibleenvironmental conditions. The phenotype may vary significantly withvariations in environment such as temperature and light level, without,however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Evera 108’. These characteristics incombination distinguish the new Rose plant as a new and distinctcultivar:

-   -   1. Upright, compact and rounded plant habit.    -   2. Dark green-colored leaves.    -   3. Large double bright yellow-colored flowers with numerous        petals per flower.    -   4. Flowers held upright on strong and erect peduncles.    -   5. Good postproduction longevity.

Plants of the new Rose plant can be compared to plants of the Rosecultivar Evera 116, disclosed in U.S. Plant Pat. No. 16,956. Inside-by-side comparisons conducted in Denmark, plants of the new Rosediffered from plants of the cultivar Evera 116 in the followingcharacteristics:

-   -   1. Flowers of plants of the new Rose had more petals per flower        than flowers of plants of the cultivar Evera 116.    -   2. Plants of the new Rose and the cultivar Evera 116 differed in        flower coloration as plants of the cultivar Evera 116 had softer        yellow-colored petals.
